'SPECIFICATION forming part of Letters Patent No. 397,989, dated February 19, 1889. Application iled June 7, 1888. Serial No. 276,406. (Na model.)4

T0 a/ZZ whom 7125 may cmwcrn:

Be it known that I, FRDERICK LATULIP, of Syracuse, in the county of Onondaga and State of New York, have invent-ed certain new and useful Improvements in Springs; and I do hereby declare that the following is a full, clear, and eXact description of the in'vention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form part of this specih'eation.

Myinventon relatcs to an improvement in rocker-springs, and more partieularly as an improvement on the spring' set forth and claimed in Patent No. 355,709, granted to me January l, 1887. Heretofore rocker-springs of this class have been formed in the shape of an S, with the opposite ends of the spring rolled back upon themselves to form horizontal eyes falling in. the same plane with the body of the spring, the spring being secured in position by screws or the like passed through said eyes. This old manner of fastening the s1;rings'is subject to great dit'ficulties and objections. The serews or nails employed have to be exeeedingly long, and henee the strength of the fastening is greatly impaired, as said screws or nails are liable to become broken or bent, and as but one eye can be formed at each end of the spring' but one screw or nail can be employed to fasten an end. The inner edges of this form of spring are apt to bear and rub against the surfaces to which they are secured when the rockers are operated, and hence wear the same and create unpleasant noises, and it is difficult to bend or roll the metal to form the eyes. It has also been eustomary to secure S-shaped Springs at their opposite ends to a rocker and a base by means of ln'ackets secured, respeetively, to thcrockcr and base and provided with laterally-extending lugs, to which the ends of the spring are secured; but this mode of fastening is cxpensive and requires an excessive number of parts when compared with the device herein shown.

The object of my invention is to provide an improved spring which shall be exceedingly cheap and simple in construction and overcome the obj ections to the springs of this class heretofore in use, and which shall be especially adapted for connecting the rockers of chairs, cradles, or the like to the stationary bases supporting the same.

lVith these ends in view my invention consists of a spring composed of a continuous spring metal bar curved in the shape of an S, and having its opposite ends turned at right angles on the same side of the bar and bent laterally into a plane beyond the edge of the bar, each turned end being provided with one or more transverse apertures, whereby the spring is secured to the rockers and base, and the body of the spring is kept away from the same without the n ecessity of using' brackets or the like for this purpose.

Referring to the accompanyng drawings, Figure 1 is a Vertical transverse sectional vi ew showing' the attachment of the spring to a roeker and its station ary support or base. Fig.

2 is a plan view of the same, and Fig. 3 is a detail. plan view of the spring.

In the drawings, the reference-letter A indicates the stationary base of a rocking-chair, cradle, or the like, and B denotes the rockers mounted on said base.

C indicates my improved spring, consisting, essentially, of spring metal loops ZZ, standing' in Vertical planes and connected at opposite ends, respectively, with the base and rocker. To embody this feature in its simplest form,

I construct said spring of a continuous bar of steel or other suitable spring' metal, bent at its central or main portion into the shape of an S and curved reversely at opposite ends in a uniform plane, said end portions forming the loops Z Z. The extreme ends e e' of the spring are bent laterally and turned at right angles, so that their flat sides will be in planes at right angles to the planes of the similar sides of the main portion of the spring, and each of said turned and laterally-bent ends e e' is provided with one or more apertures,, whercby the sp ring can be secured in position by serews or other means. The turned ends c e' are located 011 opposite sides of and preferably in proximity to the central portion of the bar, and are bent laterally upon the-Ioo same side of the spring a suitable amount, so that when the ends are secured to the rockl ers and base, rcspeetiveluxi', with their flat faees bearing' against the same, the inner edge of the spring will be heid a suitable distanee from the sides of the roekers and base, and thns all 'frietion between the sanle will be avoided and a great' ('iiliicuilty heretofore experieneed overeome. The bent end e of the spring attaohed to the roeker can be fastened by a single sc'ifew or bolt; but the bent end e', attaehed to the base, is preferabiy longer than the opposite turned end e, and provided with two or more apertures, whereby two or more seren's or boits ean be einpioyed to seeure said end to the stationary base where the inost strain oecurs.
